§ 42. Mr. Randall
asked the Secretary of State for the Environment what is the estimated cost of comprehensive loft insulation in public sector housing.
§ Sir George Young
It is estimated that it would cost about £170 million to install 100mm loft insulation in all local authority dwellings in Great Britain which at present have no more than 25mm thick of insulation, assuming a cost of £100 per dwelling. (Dwellings with greater thicknesses of existing loft insulation are likely already to be saving a considerable amount of heat). No figures are available for the public sector as a whole.
